The compliance zone comprises a plurality of through openings that are filled with one or more filler pieces comprising a low modulus material, all of which are located within three inches of a face section measured along a front-to-back axis of the golf club head.

Abstract: A method of manufacturing a golf club head with a plurality of stiffening members proximate the face, and particularly solid rods or a plate with one or more cutouts, is disclosed herein. The method includes the steps of preparing a wax of a golf club head body having at least one through-hole, a hollow interior, and at least one receiving pocket, preparing waxes of one or more stiffening members, inserting the wax of the stiffening members into the through-hole and seating its opposite end in the receiving pocket, bonding each of the stiffening members to the body with an adhesive material to form a combined wax mold, and casting a golf club head from the combined wax mold.

Abstract: A golf club head, preferably a putter head, comprising at least one structural support member is disclosed herein. The structural support member has a smooth, organic-looking aesthetic, with a continuously changing curvature along its spline and at least one surface, and preferably connects one portion of the golf club head to another portion. Where the support member connects to other portions of the golf club head, the surfaces of the member have a curvature that changes smoothly and continuously, lacking any sharp corners. The support member may be part of a lattice structure formed via binder jetting.

Abstract: A golf club head with a channel sized to receive one or more adjustable weights and an external support structure that bridges, and thereby supports, the channel without unduly interfering with weight adjustment is disclosed herein. The support structure, which includes one or more stiffening members on the exterior of the golf club head, improves the sound quality of the golf club head, and is particularly useful to attenuate the lower frequency mode shapes associated with slider channel geometry in golf club heads.

Abstract: A golf ball with improved durability is disclosed herein. The golf ball has a core comprising a polybutadiene material and methyl methacrylate, butadiene, styrene (MBS) with a weight percentage of MBS ranging from 0.5 to 5 weight percent of the core.

Abstract: A method and system for determining concentricity of a multiple layer golf ball are disclosed herein. One or more images of a golf ball are generated using an X-ray source, a camera or a digital detector, and an image intensifier. An edge detection algorithm is preferably utilized. The method also includes calculating Y,Z center coordinates of the a best fit diameter or ellipse of the inner edge layer and outer edge layer of the multiple layer golf ball.
